On other side, driver may request for clock with/without con_id and dev_id, and it is expected that platform should respect this request and return the requested clock handle. Now, when using device tree, the format of the device name created by OF layer is different, ".", assuming that the device-tree "reg" property is specified. This causes the look-up failure for clock node in dcan driver To fix this add new dcan clock alias for using device-tree.
